Read the tutorial below to learn how to use the alignment tools to move and precisely position objects (layers). You can also watch our video tutorial.
Rulers are shown along the edges of the Image Window. Guidelines (as well as the Grid) are nonprinting supporting horizontal and vertical lines which are displayed over the image (they will not appear on the final result).
To create a horizontal/vertical guideline, place a cursor over a corresponding ruler, and holding the left mouse button, drag a blue line which appears under the cursor. You can move the guidelines with the Move tool (the cursor will turn into ).
To create a copy of a guideline, hold down the Shift+Alt keys while moving it.
To remove a guideline, drag it outside of the Image Window.
To adjust the alignment settings, use the Workspace menu in the Control Panel:
Marks on the rulers indicate the position of the cursor.
To change the origin (zero), place the cursor over the intersection of the rulers in the upper left corner of the Image Window and drag diagonally to the desired point in the image. To restore the default origin, double-click this corner.
Click in the upper right corner of the program window or select File - Preferences... to open the Preferences dialog box. Switch to the Guides & Grid tab to adjust rulers, guidelines, and grids.
